COLLAPSIBLE STOVE.

Specification of Letters Patent.

, Patented July 25, 1916.

Application fi1ed October 13, 1915. Serial No. 55,610.

To all whom it may concern.-

Be it known that I, EASTER M. HUGHES, citizen of the United States, residing at Seattle, in the county of King and State of lVashington, have invented a certain new and useful Improvement in Collapsible Stoves, of which the following is a specification.

My invention relates to improvements in collapsible stoves, and the object of my improvements is to provide a stove and a stovepipe therefor whose several side walls and top wall shall be made of sheet metal, as of sheet iron or sheet steel, all the Walls of the stove being joined together by hinged joints to make a continuous series of plates that may be folded side by side, and the stovepipe therefor being of square cross-section and its four side-walls being likewise joined to adapt them also to be folded together, whereby all the parts of both said stove and said stove-pipe may be compactly disposed in a single package that may be conveniently transported. I accomplish this object by devices illustrated in the accompanying drawings wherein Figure 1 is a view in perspective of a stove embodying my invention as it appears ready for use with its stove-pipe attached thereto; Fig. 2 is an enlarged view of the same in vertical section on broken line m, a; of Fig. 1; Fig. 3 is a plan view in reduced scale of the several plates forming the several side-walls and the top wall of the stove as they appear when all of them are disposed in the same plane; Fig. 4 is a plan view of the four plates forming the side walls of a stove-pipe as they appear when all of them are disposed in the same plane; Fig. 5 is a view of the edges of the top wall plate and side wall plates of the stove as they appear when folded; Fig. 6 is a view of the edges of the four platesfo-rming the side walls of said stove-pipe as they appear when folded; and Fig. 7 is an enlarged fragmentary view in perspective of associated details of my invention.

Referring to the drawings, throughout which like reference numerals indicate like parts, a plate 8 and a plate 9, whose adjacent edges are hinged one to the other, serve to form the top wall of a stove, and the back edge of the plate 9 is hinged to thetop edge of a plate 10 which forms the back side wall of said stove, and hinged'to the right hand end edge of the plate 10 is one end edge of a plate 11 which forms the right hand side wall of said stove, while to the left hand end edge of the plate 10 is hinged one end edge ofa plate 12 which forms the left hand side wall of said stove while to the other end edge of said plate 12 is hinged to one end edge of a plate 13 which forms the front side wall of said stove, while the other end edges of the plates 11 and 13 are adapted to be joined together in the manner illustrated in Fig. 7 by means of a wire rod 1 1 which is disposed to project downwardly through hingedike members 15 and 16 formed on plates 11 and 13 respectively.

Fig. 3shows the plates 8, 9, 10, 11, 12 and 13 as disposed in a horizontal plane but to dispose them to form a stove as shown in Fig. 1, the plate 10 is swung downwardly to a vertical position, carrying with it the plates 11, 12 and 13 to such vertical position, then the plates 11 and 12 are swung forward to form respectively the right hand and left hand vertical side walls of said stove, then the plate 13 is swung to a position beneath the front edge of the plate 8 to form the front side wall of said stove, where its right hand end edge engages with the front end edge of the plate 11, as illustrated in Fig. 7, whereupon the wire rod 14: is projected downwardly through the hinge-like members 15 and 16 of the plates 11 and 13 respectively to unite securely said plates 11 and 13, said wire rod 1 1 being su'lliciently long to project its upper end portion freely through a hole 17 formedin a corner portion of the horizontally disposed plate 8 thereby to serve as a dowel pinwhich may aid in maintaining the associated plates in their normal positions without preventing said plate from being swung upwardly and backwardly for the purpose of putting fuel into the stove.

In the lower portion of the plate 13 in a positionequidistant from the plates 11 and 12 is an opening 18 which is provided with a vertically slidable plate 19 that is guided in its movements by cleats 20 and-21 thereby adapting said plate 19 to be raised and lowered to control, in an obvious manner, the admission of a draft of air into the stove.

In the rear portion of the plate 9 of the top side of the stove, adjacent to the edge of the plate 10, a square section is removed to form. an opening 22 through which smoke may pass upwardly into and through an associated stove-pipe (of square cross-section) side as shown in Fig. 6.

lVhen the stovepipe is to be placed in its position to connect with the opening 22 then the plates 23, 24, 25 and 26 are disposed to form a square tube with the outer edge of the plate 23 joined to the outer edge of the plate 26 and there secured by a wire rod 27 then the lower end portions of the plates 23, 24, and 26 are disposed to project downwardly through said opening 22 so that the back edges of the end portions of the plates 24 and 26 engage with the inner side of the plates 10, while the lower end portion of the plate 25 is disposed to engage with the exterior surface of the plate 10, as more clearly shown in Fig. 2, thus causing the major portion of the weight of the stove pipe to be supported by the plate 10 comprising the back side wall of the stove, while the stove-pipe is held in an upright position.

While I have shown only one means for maintaining the stove-pipe in its normal operative position, diiferent means that will readily suggest themselves to those skilled in the art may be employed.

A stove embodying my invention requires no bottom side plate since it is designed to be disposed with thevlower edges of the plates 10, 11, 12 and 13 set directly upon the surface of the ground thus serving as a bottom for the stove.

When all the plates are assembled to form the structure as shown in Fig. 1, and disposed upon the ground in a desired location the plate 8 may be swung upwardly and backwardly and the vertically slidable plate 19 may be raised to give a desired draft of air and fuel may then be placed within the stove through the open top and the fire kindled and thereupon the plate 8 may be swung downwardly to close such open top.

Manifestly, if it be desired to lengthen the stove-pipe to give increased draft, then one or more sections of similar stove-pipe may be attached to the top edges of the stove-pipe embodying the plates 23, 24, 25 and 26.

When it is desired to move the stove to a new location the stove-pipe is lifted off the stove, then the wire rod 27 is drawn out of the joined edges of the plates 23 and 26, then the four plates 23, 24, 25 and 26 of the stove-pipe are folded into the form shown in Fig. 6; then the wire rod 14 is withdrawn from the adjacent edges of the plates 11 and 13 whereupon the plates 8, 9, 10, 11, 12 and 13 are folded into a compact form as illustrated by Fig. 5, and thereupon the two packages of the forms of Fig. 5 and Fig. 6 may be placed one on top of the other to form a single small package that may be conveniently transported.

Obviously, changes maybe made in the forms, dimensions and arrangement of parts of my invention without departing from the spirit thereof.

l/Vhat I claim is:

A sheet metal collapsible stove of the class described embodying a blank plate including a vertical back wall; two plates, one end of each of which is hinged to a different one of the opposite ends of said back wall and each of which is disposed at right angles to said back wall to form opposite vertical side walls; a fourth plate having one of its ends hinged to the front end of one of said vertical side walls and its other end releasably connected with the front end of the other of said vertical walls whereby said fourth one of said "vertical walls; a top side wall comprising two members hinged one to the other, one of said members being hinged to the top edge of said vertical back wall to adapt said top side wall to engage with the top edges of said side walls and said front wall, the releasable connection between the front and end wall engaging the front section of the top wall, an outlet passageway for smoke disposed to extend through said top side wall; and a collapsible stove-pipe removably associated with said outlet passageway for smoke.

In witness whereof, I hereunto subscribe my name this fourth day of October A. D. 1915.
